  title={Direct electrochemical reduction of titanium dioxide to titanium in molten calcium chloride},
  author={George Zheng Chen and Derek John Fray and Thomas William Farthing},
Many reactive metals are difficult to prepare in pure form without complicated and expensive procedures. Although titanium has many desirable properties (it is light, strong and corrosion-resistant), its use has been restricted because of its high processing cost. In the current pyrometallurgical process—the Kroll process—the titanium minerals rutile and ilmenite are carbo-chlorinated to remove oxygen, iron and other impurities, producing a TiCl4 vapour. This is then reduced to titanium metal… Expand
Reduction of titanium and other metal oxides using electrodeoxidation
Abstract Many reactive and refractory metals are currently produced industrially by reducing their compounds, including oxides, using a more reactive metal. In some cases, where there is substantialExpand
Titanium dioxide and other reactive metal compounds are reduced by more reactive metals to form pure metals. These are expensive and time consuming processes which makes these metals very expensive.Expand
